Fnb double charging fees

Fnb has proven to be ******* and the thing is I have no control over them taking money from my account.

So during the month of April I purchased vouchers and I noticed a fee was being taken wach time. I chatted on the fnb chat and queried this with them and they confirmed that it was for these vouchers but I weren't getting any joy with them answering if I would be charged again with my service fees so I called in. The consultant confirmed that since it's being taken with each purchase,they won't charge again with the bank fees. But low on behold,with my fees for my account,another 200 was deducted as service fees. I called in and queried and they said it was for the vouchers I think explained how the fee was being taken with eqch voucher then I was advised to email complaints.

I laid a complaint on the 18 April 2025,of which i got a response but we kept going back me showing them screen shots and asking them to pull the records of my conversation because technically they have now billed me twice. Until this day,no response,I emailed again on the 22,23rd and 29 April 2025 and I'm just being ignored
